C ++ exercises have solutions (sample code)

Besides the Python, Java exercises, TipsMake.com also summarizes for you some basic C ++ exercises to practice more in the process of learning C ++ programming language.

This C ++ exercise list is divided into 9 sections, each with 3 to 5 items, with increasing difficulty levels. Initially you will "boot" with very basic C ++ exercises, such as simulating the multiplication, printing the amount, checking a set of 3 numbers to see if it is the edge of a triangular triangle, calculating the circumference, area of ​​that triangle.

Gradually, it will be more difficult to create and manage student lists, documents, print or perform other tasks as required by the lesson. Even draw a graph of trigonometric functions.

Question 4: Calculate the distance of the positive integer n

Write recursive function to calculate the factorial of the positive integer n. The main function uses this function and can run several times to calculate for many different numbers entered from the keyboard. The request to check the input data must be a positive integer. The formula calculates the factorial of n: n! = 1.3 . n if n is odd and n! = 2.4 . n if n is even.

Sample code:

 while (!feof(fp))5 
 
 while (!feof(fp))4 
 
 while (!feof(fp))3 
 
 while (!feof(fp))2 
 
 while (!feof(fp))1 
 
 while (!feof(fp))0

 {fscanf(fp,"%d",&x);2 
 
 {fscanf(fp,"%d",&x);1 
 
 {fscanf(fp,"%d",&x);0

 if (max 
 
 if (min>x) min=x;6 
 
 if (max 
 
 if (min>x) min=x;5

Question 5: Write recursive function to solve the problem of Hanoi tower

Write recursive function to solve the problem of Hanoi tower: It is necessary to transfer n towers from position A to position B using position C as an intermediary. Requirements: Only one floor can be transferred at a time, only the A, B, C positions can be used to place the tower floors, not the raised floor on the small floor. The main function uses this function and can run several times to calculate for many different numbers entered from the keyboard.

Sample code:

 if (max 
 
 if (min>x) min=x;4 
 
 if (max 
 
 if (min>x) min=x;3 
 
 if (max 
 
 if (min>x) min=x;2

Question 3: Enter, print array, count paragraphs according to criteria

Write a function to import arrays, a function that prints elements of an array to the screen, an increase in the number of paragraphs, a function that finds the longest increase in the array. The main function uses these functions to enter the element n array, print the array, print the number of increments and the longest increase in the array.

Sample code:

 getch();1 
 
 getch();0

Question 4: Enter, print, calculate 2 matrices

Write a function that imports the elements of a 2-dimensional matrix, a matrix printing function in column rows, a function that multiplies 2 matrices. The main function uses these functions to enter the MxN size matrix A and the NxP size matrix B. Print matrix A and B and matrix C are the product of 2 matrices A and B.

Sample code:

 {char maso[10];0

 char ht[25];8 
 
 char ht[25];7

Question 5: Enter, print square matrix, determinant

Write a function that imports elements of a square matrix of n-level, a matrix printing function according to the column row structure, a function of deterministic matrix matrix n. The main function uses these functions to enter the square matrix of n levels, prints the matrix, calculates and prints the determinant of that matrix.

Sample code:

 sv bg;9 
 
 sv bg;8 
 
 sv bg;7 
 
 sv bg;6 
 
 sv bg;5 
 
 sv bg;4 
 
 sv bg;3 
 
 sv bg;2 
 
 sv bg;1 
 
 sv bg;0
